Party good to follow (3)
I believe the answer is:
dog
'follow' is the definition.
(I've seen this in another clue)
'party good' is the wordplay.
'party' becomes 'do' (do is a kind of party).
'good' becomes 'g' (abbreviation).
'do'+'g'='DOG'
'to' is the link.
(Other definitions for dog that I've seen before include "Contemptible man" , "Domesticated canine" , "Shadow" , "Follow - canine" , "Domestic animal" .)
